Paper Abstract

Two monochromator sources were used during the AXAF calibration at Marshall Space Flight Center's X-ray Calibration Facility. Data acquired using these sources require special analysis owing to large spatial variations in the monochromators' beams and to higher-order contributions to the spectral content. A description of the two monochromators is given, followed by a discussion of the spectral and spatial content as monitored by beam- normalization detector flow proportional counters. Emphasis is given to the methodology employed in determining the spatial content through fits to beam uniformity measurements. A model is described which adequately represents the beam spatial properties over the range of source conditions encountered during calibration.
